A plate or novel method of securing the vibrating mounting member 9 for supporting the staarmature of the rectifying relay and the tionary contacts 10, 11, 12 and 13 of the restationary contacts, with which active conlay and also for pivotally supportingthe 50 tacts carried by the armature co-operate, to armature B is constructed of suitable non-' a single mounting piece which is carried by magnetic material and is secured to the cores the extended cores .of the electromagnets. 14 and 15 of the electromagnets 2 and 3 by This method of mounting prevents the armameans of extension cores 16 and 17 The exture oi the relay from getting out-of a-djusttension. cores 16 and 17 are provided with threaded shanks '18 which have K screwthreaded engagement with holes drilled and V tapped in the cores 14 and 15, as shown most clearly in Fig. 1.

The armature B is constructed of two plates 18 and 19 similarly shapedand having their central portions formed so that when the two plates 18 and. 19 are riveted together. a circular opening 20 is formedwhich extends across thewidth ofithe said armature B.

A washer is placed between the staked portion of the stud and the shouldered portion of the bushing 62. The stud 60 has a hole drilled and tapped to receive a screw 66, which screw 66and washer 67 are used to clamp the conductive strip 58 between the said washer 67 and stud 60. Av U- shaped permanent magnet 68 is fastened 'to the yoke 5 by means of a screw 69. The free end or leg 70 of the U-shaped permamm magnet 68 extends over the armature B in'proximity thereto for'the customary \purpose.

Referring to Fig. 10, X diagrammatically represents the .rectifier relay of Figs. 1 to .9, inclusive, for rectifying the source of alternating current supplied through terminals Y, and Z diagrammatically represents a pole changer for changing the rec tified source of uni-directional current into alternating current of the desired frequency. The, operating magnet 210 of the pole changer Z is bridged directly across the secondary winding of the transformer, and

therefore, of course, is supplied with al-' ternating current, and likewisethe magnets of the rectifier X are bridged across the terminals of the secondary winding of the transformer. L

Assuming that the armature of the device X is in the position shown in the drawings,

then a positive impulse willbe'transmitted from terminal 212 of the transformer,

through the lamps in parallel, through stationary contact-205 andmovable contact 201 of the rectifier to the conductor 207, and a negative impulse of current will be supplied from terminal 211 of the transformer, through stationary contact 202 and movable contact 200 of the rectifier relay X to conductor 206. Now, when an impulse of current is induced in the secondary winding in the reverse direction, the armature of the device X will move its contacts 200 and 201 to an alternating position, that is, to

.a position in which contact 200 engages stationary contact 204, and contact,201 engagesstationary contact 203. In this position, a positive impulse of current will be transmitted from terminal 211, through stationary contact 203, movable contact 201 to conductor 207 and a negative impulse of current will be transmitted from ter-,

minal 212, through the lamps in parallel, stationarycontact 204, movable contact 200 to conductor 206. From this it will be seen that positive impulses of current are always supplied to conductor 207, while nega tive impulses of current are always supplied to conductor 206.

The contacts 220; and 221 of the pole changer Z are operated by the magnet 210 of the changer and operate to intermittently supply positive and negative current from the conductors 206 and 207 to" the terminals 222 and 223, thereby producing alternating current of a frequency different than the frequency of the original source of supply. The device Z may be arranged to vibrate at any desired frequency.
